i added two users: foo & bar, but i will still receive their mails due to the wildcard @example.com. Is it possible to exclude foo@example.com & bar@example.com -mails from beeing delivered to my mailbox?

DESCRIPTION
The optional virtual(5) alias table rewrites recipient addresses for
all local, all virtual, and all remote mail destinations. This is
unlike the aliases(5) table which is used only for local(8) delivery.
Virtual aliasing is recursive
